.RADIATORS'AND THE LIKE.

Patented Aug. 28, 1906.

Application filed November 22, 1804- Serial. No. 233.878.

To all whom it may concern:

Be it known that I, RO ERT ERNEST AT- KINSON, a subject of the King of Great Britain and Ireland, residing at 57 Evington road, Leicester, England, have invented certain new and useful Improvements in Control-Valves forRadiators and the Like, of which the following'is a specification.

This invention relates to controlling and stop valves for radiators and like purposes, the object being to provide an automaticallyoperated valve for controlling the supply of steam to a radiator or other vessel accord ingly as the demand for such steam arises,

such automatic valve, however, being provided with means b which its amount of opening may be re u a'ted or adjusted at any time in order to al ow an attendant or occupant oi the roomin which the radiator or vessel is situated to more easilycontrol the tern erature of the roorh.

T e object is also to so arrange the adjusting devices for the valve as to facilitate the detection of tampering with the valve on the part ofthe attendant or other unauthorized erson. v

The invention is applicable to the auto- J matic control of steam, water, or other fluid either to or from a vessel and is not confined in its application to a radiator or any special type of radiator.

The accompanying drawings illustrate forms ofthe invention.

Figure l is a vertical section illustrating the application to a radiator. Fig. 2 is an in Fig. 1. Fig. 3 is a vertical section of an 7 two independent valves,

alternative form of pointer-manipulating de Y vice. Figs. 4 and 5 are respectively vertical section and end elevation of another alternative iormoi pointer and dial. Fig. 6 is a horizontal section of the device, illustrating nitely opening or closing the radiator to steam.

" The automatic valve a'is screwed upon the.

erably carried on a spindle V a stuiii'ng-box and having on itsinner end a end of an iron or like rod 0, the opposite end of the rod being screwed to the closed end of a surrounding copper or "like expansion-tube d, the open end of which is screwed to the valve-casing. .This expansion-tube (1 may be arranged in any suitable manner in conjunction with the radiator e, so as to agree approximately in temperature therewith. It will thus be obvious that as the copper. tube (Z becomes hot or cold it will expand or contract, and thus by means of the iron rod 0 -move the valve a to or from its seat, and thus control the supply of steam to the radiator.

In order to enable the opening of the valve a to be regulated at any time by means readily accessible to any one in the. apartment containing the radiator, the valve a is screwed on the end of the iron rod 0 and adapted to be rotated thereon by means of an exterior han dle, pointer, or wheel. A handlef' is shown in Figs, 1. and 2 with a pointer f attached to it. A wheel g is shown in Fig. 3 with the pointer f, Figs. 4 and 5. A pointer f in any case is arranged to move over anindexi or dial 1', divided into degrees, and, if desired, marked with such indications as warm, hot, or the like, corresponding to the limit of opening allowed or set for the valve (1.. The pointer f or device carryin the same is pref passing through cross-pin Z, engaging in slots or between pins on the valve a, so as to enable the latter to be rotated in either direction and cause it to the screw-thread'm thereon, which is preferably left-h'anded to. enable the pointer to be moved clockwise to increase e supply of steam.

The pointer f and dial j are shown in Figs. 4; and 5 inclosed in a casing n, provided with a removable glass top or lid 0, which may have a bayonet-joint connection or be secured by screws; o

In order to prevent tampering with the valve a after it has been initially set by the engineer, the latter at such setting may note -.the number or degree on the dial to which the pointer f indicates when the valve 0. is closed or screwed down on its seat or in any other fixed or definite position. This number may be keptin an index, and at a subseuent inspection will reveal at once whether t e valve has been tfiIIlPQIG Clifllth.

while a pointer f alone is shown in' move longitudinally on the iron rod 0, due to The improved automatic controlling-valve is combined with a'definite stop-valve. Said stop-valve is situated in the same casing, as illustrated by b, Fig. 1, and is preferably of the screw-down type having a very quick pitch, as its object is to entirely close or open the passage to steam and not to partly regulate the same.

When the invention is applied to a radiator which is situated Within a recess in a Wall or Within a cabinet in order that the dial may be brought to the front, the'spindle lc,-on which the pointer f is carried, may be divided, as shown in Fig. 6, the divided portions being arranged at right angles and-connected by bevel-gearing r or by universal joints or in any other suitable manner. I

It is to be understood that the invention is not confined to the form of thermostat or other details of construction hereinbefore referred to, byway of example, but that the same may all be modified to suit the'size or a type of radiator or other apparatus to which trol of fluid either to the automatic controlling-valve or combined automatic controlling. and'hand-stop valve is to be applied or the position thereon in which it is to be placed; a

The'invention also is applicable tothe-con l or from the radiator or like. apparatus. I

Having thus described my invention, what I claim as new, and desire to secure by-Letters Patent, is I The combination with a radiator of a combined handoperated and automatic device for controlling the supply of heating fluid thereto, and adapted to be connected at one point thereon, comprising a single casing adapted to be screwed-into an opening near "the bottom of the radiator, an inlet and an 40 outlet to said casing the latter communicating with the radiator, a-hand-operated quickpitch screw-down stop-valve and a thermostatic valve insaid casing, thermostatic members for the latter projecting into the radiator, a spindle for adjusting the thermostatic valve, ahandle and pointer on said spindle outside the casing and a scale for indicating the adjustment of the valve.

In witness whereofl have hereunto set my 5 hand in presence of two witnesses.
